Steel and aluminum are the two most popular materials used in the construction of industrial stairs and walkways. But aluminum provides many characteristics that are unmatched by other metals, making it ideal for jobsite use.

6000 Series Aluminum Alloys

Our REDD Team access systems are typically constructed from 6000 series aluminum alloy with 6061-T6 for structural strength. With the addition of magnesium and silicon, 6061 alloy is an excellent substitute for mild steel products which are substantially heavier. 6061 is one of the least expensive and most versatile aluminum alloys available. It’s heat-treatable and tough but can be easily welded and joined.

It has a high resistance to corrosion from environmental conditions, making it popular for marine projects and a wide range of industrial applications.

Many alloys gain strength from thermal treatment and aging. 6061-T6 is no exception; heat treatment gives it excellent structural strength and toughness. It also offers good finishing characteristics and responds well to anodizing. Aluminum 6061-T6 alloy conducts and dissipates heat well.

And, since it can be extruded, it can be formed into almost any imaginable shape. These qualities make it ideal for the fabrication of stairs, walkways, bridges and many other similar structures.

Why Choose Aluminum?

The biggest difference between steel and aluminum is obviously weight. Steel is typically 2.5 times denser/heavier than aluminum. This means that aluminum access structures will be easier to handle and less expensive to ship. Other significant differences include:

Strength. Aluminum has a high strength-to-weight ratio; its mass and weight is roughly 35% that of iron and 30 % that of copper. It is more malleable and elastic than steel. Steel is a very tough and resilient metal but cannot generally be pushed to the same extreme dimensional limits as aluminum.

Malleability. Complex shapes can be obtained in one-piece extruded sections thereby avoiding mechanical joining methods. This makes the stair frame components stronger and less likely to loosen over time.

Corrosion Resistance. One of aluminum’s greatest attributes is that it is naturally corrosion resistant without additional treatment. It doesn’t rust. This is due to the presence of a thin, naturally occurring protective film of aluminum oxide that bonds to its surface. Steel usually needs to be painted to protect it from rust and corrosion, especially if it will be used in a moist or damp environment. Aluminum can be used without any finish coating or painting, but can be anodized, painted or powder-coated if desired.

Non-combustible. Aluminum does not burn and, even at extremely high temperatures, it does not produce toxic fumes.

Recyclable. Aluminum can be recycled repeatedly, quickly, and cost-effectively without losing any of its characteristics. The recycling of aluminum uses less energy and can offer substantial costs benefits. Our aluminum stairs and other access products meet the guidelines of the U.S. Green Building Council and are appropriate for LEED credits.
